Years ago i was given a mint condition Gibbons with 1917 dated No:23 base plug. The spring wasn't marked like some. Unfortuantly back then i didn't know much about Gibbons grenades and sold it on later thinking it was some made up grenade tinkered with, but what i had was a very clean example with its light blue galvanised finish. Now i am in the process of getting another but just the body with the finish. Reading through some of the posts i saw it mentioned that springs were available as a copy. Anyone know where you could get a spring, lever and base plug from, and the thread size of the round headed brass screw that hold the spring.
